Summary:
The pacingTimerTickInterval transport setting conflates two options: the minimum interval a pacer can use, and the resolution of the underlying timer. This means that a higher value leads to lower timer resolution and less pacing accuracy.
This change adds a separate parameter for the timer resolution to ensure that a larger pacing tick does not degrade the pacer accuracy.

Summary:
The idea here is to add a notion of time-based sampling of certain QUIC_STATS. This allows accounting to be done via consistent distributions for comparisons.
For now limit to the server, and only implement for inflight bytes, SRTT, and CCA bandwidth.

Summary:
The previous implementation defined a `struct SourceIdentityKey` which was
used as input to a hashing function. Consequently, we needed to be careful about
the internal layout of the struct to ensure that it had a unique object
representation. We included some `static_assert`s to ensure this.
Platform-specific differences on `struct sockaddr_storage` made this difficult
to enforce.
This diff changes the implementation of the source identity hash to manually
build a serialized representation of the previous SourceIdentityKey. We manually
pack the structure into a byte array.
